Because they combine hardness and strength with resistance to corrosion, so they will be long lasting and stronger
Surgical instruments are made from stainless steel.
Surgical instruments are made from steel. Steel is an alloy made of mostly iron, with other elements to give it special properties. Surgical steel is made from iron, chromium, nickel and molybdenum.
They are made from surgical steel, and surgical steel is made of 440C stainless steel.
Surgical instruments are tools or devices that perform such functions as cutting, dissecting, grasping, holding, retracting, or suturing. Most surgical instruments are made from stainless steel.
It is made of surgical stainless steel.
Stainless steel is commonly used to make kitchen appliances, cutlery, cookware, surgical instruments, industrial equipment, and automotive parts due to its corrosion resistance, durability, and sleek appearance.
Stainless steel.
Most tattoo needles are made of some grade of stainless steel. Surgical stainless steel is very common in tattooing needles.
The more chromium used in making stainless steel, the softer the alloy becomes, which is undesirable in the manufacturing of surgical instruments. Therefore, the mix required to make quality medical instruments is very specific and has well defined parameters.
The improvement from iron to stainless steel is that another metal alloy had been created. This new alloy allows for improvements to life in general since it has other uses than that of ordinary iron. Surgical instruments come to mind, they would not exist as we know them without the evolution of metallurgy which made stainless steel and many other useful alloys possible.
Barbells are made of surgical stainless steel (316 LVM), Titanium, PTFE or Bioplast.
Hand cutting instruments are manufactured from two main materials: carbon steel and stainless sateel. In addition, some instruments are made with carbide inserts to provide more durable cutting edges. Carbon steel is harder than stainless steel, but when unprotected, it corrodes. Stainless steel remains bright under most conditions, but loses a keen edge during use much more quickly than does carbon steel. Carbide, although hard and wear resistant, is brittle and cannot be used in all designs. Other alloys of nickel, cobal, or chromium are used in the manufacture of hand instruments, but they usually are restricted to instruments other than those used for the cutting of tooth structures.Source : Sturdevant's Art ans Science of Operative Dentistry .
